syb package on Hackage does not work with 6.12
The syb package on Hackage (0.1.0.1) has
-package-name syb, which was needed for 6.10 but breaks with 6.12. The version in darcs lacks the flag, which works for 6.12 but will break with 6.10. We need to upload a version of syb that works with both 6.10 and 6.12 to Hackage before the 6.12.1 release.
